Answer:
y - 10 = 8(x-9)
Step-by-step explanation:
m= (10-2)÷(9-8) =8
y-y1 = m(x-x1)
y-10 = 8(x-9)
Radius=sqrt(2^2+9^2)
r=9.22
equation
(x+3)^2+(y-2)^2=9.22^2
(x+3)^2+(y-2)^2=85
Following the order of operations, you first multiply 25 and 2.
Now you have 8+50-45
Then, you add and subtract left to right.
So, 58-45
58-45=13 CDs
This is a 1, 1, √2 triangle, as the two leg sides are congruent.
the 1 side = 12 in measurement
Multiply 12 with √2
12 x √2 = 12√2
12√2, or (A) is your answer

Answer:
179.3 square units
Step-by-step explanation:
The area of the figure is the sum of the areas of the parts. That is, the area is the sum of the area of the rectangle, and the area of the semicircle.
__
<h3>Semicircle</h3>
The area of a circle with radius 5 is ...
A = πr²
A = π(5²) = 25π
The area of the semicircle is half that:
semicircle area = (25π)/2 = 12.5π ≈ 39.3 . . . . square units
<h3>Rectangle</h3>
The area of a rectangle with length L and width W is ...
A = LW
The width of this rectangle is the diameter of the circle, twice the radius, or 10 units.
A = (14)(10) = 140 . . . . square units
<h3>Total area</h3>
The sum of the areas of the parts is ...
total area = semicircle area + rectangle area
total area = 39.3 + 140 = 179.3 . . . . square units
